Re: Job scheduler

Hi

Execution as "guest" is expected behaviour. Per
https://exist-db.org/exist/apps/doc/scheduler#job-author you need to switch
permissions or set the SetUid/SetGid bits on the XQuery file's permissions.

Authoring Jobs

The scheduler supports jobs that are authored in either XQuery or Java:
XQuery Jobs

Jobs coded in XQuery can be user type jobs only.

An XQuery job is a standard XQuery Main Module which is stored in the
database. You configure the scheduling of the job by providing the database
path to the XQuery, for example: /db/my-collection/my-job.xq.

XQuery job's are launched under the *guest* account. If you wish to perform
tasks as another user , either switch permissions by calling xmldb:login() from
within your job, or set the SetUid/SetGid bits on the XQuery file's
permissions (see Security <https://exist-db.org/exist/apps/doc/security> for
more information).
Cheers,
JPR
